Note: These are both elastic collisions: Key
1. You are given the following data about a golf club hitting a stationary golf ball:
mass of club head = 0.350 kg
mass of golf ball = 0.046 kg
speed of club head before collision = 38 m/s
speed of club head after collision = 29 m/s
Calculate the following:
A. momentum of club head before collision: 13.3 kgm/s
B. momentum of club head after collision: 10.15 kgm/s
C. momentum of golf ball before collision: 0 kgm/s
(the ball is at rest before hitting
D. momentum of golf ball after collision: 3.15 kgm/s
E. speed of the golf ball after it is hit by the golf club: 68.5 m/s
2. You are given the following data about a bowling ball hitting a stationary bowling pin:
mass of bowling ball = 7.0 kg
mass of bowling pin = 1.5 kg
speed of bowling ball before collision = 11 m/s
speed of bowling ball after collision = 6 m/s
Calculate the following:
A. momentum of bowling ball before collision : 77 kgm/s
B. momentum of bowling ball after collision: 42 kgm/s
C. momentum of bowling pin before collision: 0 m/s (the pin at rest before striking)
D. momentum of bowling pin after collision 42 kgm/s
E. speed of the bowling ball after it is hit by the bowling ball : 35 m/
